Embodiment Construction

[0028] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0029] see figure 2 , diagram 2-1 , Figure 2-2 with Figure 2-3 , the length of the scraper holder 4 exceeds 1.5 meters, and the scraper blade 10 is very thin, with a thickness of about 0.15mm. In order to improve the uniformity of contact between the doctor blade 10 and the anilox roller 12 over the entire length, the concept of the present invention is: the cylinder shaft of the cylinder 1 is hinged with the connecting rod mechanism 2, and the connecting rod mechanism 2 is equipped with a rotary sleeve 3, and the rotary sleeve 3. There is a bearing pin 3-1 on the end face, and the bearing pin 3-1 is inserted in the shaft hole of the joint surface of the connecting rod mechanism 2. The supporting frame 5 is set on the rotating sleeve 3 and locked and fixed with the set screw 19 . The support frame 5 is a circular tube body, and the length is ...

Abstract

The invention provides a corrugated cardboard printing machine and a multipoint scraper-adjusting and ink-distributing device thereof, which can solve the problem that ink distributing is influenced because the laminating degree of a film scraper and an anilox roller are nonuniform on the full length of the anilox roller in the prior art. The technical scheme is characterized in that at least twosets of scraper frame adjusting devices are arranged on a supporting frame, each scraper frame adjusting device comprises a supporting frame guiding pipe, a supporting shaft, an adjusting nut and an adjusting handle, wherein the supporting frame guiding pipe penetrates through the supporting frame and is fixed with the supporting frame, a part of the supporting shaft is installed in the supporting frame guiding pipe, one end of the supporting shaft and the scraper frame are fixed, the other end of the supporting frame in the supporting frame guiding pipe is provided with the adjusting nut, the adjusting nut and the supporting frame guiding pipe are connected through screw threads, and the adjusting handle penetrates through the adjusting nut and is in threaded connection with the supporting shaft. In the invention, because a plurality of scraper frame adjusting devices are additionally arranged on the scraper frame, the precision adjustment of the scraper frame and the ink distributing effect are improved.

Description

technical field [0001] The invention belongs to the technical field of packaging and printing machinery, and relates to flexible ink printing equipment for producing corrugated cardboard boxes, in particular to a device for controlling the amount of ink in a ceramic anilox roller for a corrugated cardboard printing machine. Background technique [0002] Corrugated cardboard water-based ink flexible printing machine is a necessary mechanical equipment for corrugated cardboard printing in the carton packaging industry. Corrugated cardboard is printed in the printing department of the printing machine, which is a process of ink transfer. The working process is that the ink is first transferred to the anilox roller, then transferred to the flexographic printing plate by the anilox roller, and finally transferred to the surface of the corrugated cardboard by the flexographic printing plate to complete the printing. In this process, it is very important to control the amount of i...
